BACKGROUND OF THE INVENTION

1 Field of the Invention

The present invention relates to an information processing apparatuscapable of acquiring, from a device connected thereto, configurationinformation for a setup corresponding to the device according to theconfiguration information, a method performed by the informationprocessing apparatus, a program product for causing a computer tofunction as the information processing apparatus, a recording mediumthat stores therein the program product, and an information processingsystem in which the information processing apparatus and the device areconnected in such a manner that communication can be performedtherebetween.

2. Description of the Related Art

An information processing apparatus such as a personal computer(hereinafter, simply referred to as “PC”) can be connected to aperipheral device such as a printer, a scanner, or a facsimile machine(FAX) via a network or in a serial manner. In such a case, the PC isprovided with a device driver for converting data, which are created byor viewed with an application installed therein, into data that areprocessable by the peripheral device.

For example, when an image forming apparatus such as a laser printer(LP) or a multifunction peripheral (MFP) (hereinafter, simply referredto as “printer”) is connected to the PC, the PC is typically providedwith a printer driver dedicated for the printer. Accordingly, datacreated by or viewed with an application in the PC can be converted intopage description language (PDL) data that are processable by theprinter.

Generally, each printer uses a printing setup based on functions(options) provided therein, which printing setup is different from thoseof other printers. Printer functions include functions that are commonto all types of printers regardless of the machine type and/or thevendor, and functions that are determined based on option configurationsinstalled in each printer. Option configurations differ according to themachine type and/or the vendor. Each printer is dependent on its optionconfiguration and can have different functions from other printers.

In the conventional technology, there is a printer driver capable ofresponding to any type of printer by specifying setups only forfunctions common to all types of printers with different optionconfigurations, without depending on each of their optionconfigurations.

Furthermore, there is also known a technology in which the PC performsbidirectional communication with the printer, acquires the optionconfiguration installed in the printer, and reflects the acquired optionconfiguration in the printer driver for a printing setup to make use offunctions of the printer.

This technology is disclosed in, for example, Japanese Laid-Open PatentApplication No. 2002-259085 (Patent Document 1) and Japanese Laid-OpenPatent Application No. 2002-175258 (Patent Document 2).

Patent Document 1: Japanese Laid-Open Patent Application No. 2002-259085

Patent Document 2: Japanese Laid-Open Patent Application No. 2002-175258

However, the above-described printer driver capable of responding to anytype of printer can specify setups only for the functions common to theprinters. Hence, only some of the functions of each printer can be used.

In the conventional technology disclosed in Patent Documents 1 and 2,the printer driver can specify detailed setups for functions of printersthat are recognized beforehand, but not for printers that are notrecognized beforehand.

In a network system managed with SNMP,the configuration information storage 204 is typically referred to as anMIB (Management Information Base). Hereinafter, the configurationinformation storage 204 is referred to as an MIB.

FIG. 4 is a block diagram of the printer driver 104 in the computer 10according to an embodiment of the present invention. As shown in FIG. 4,the printer driver 104 is connected to the manager 106. The printerdriver 104 includes a user interface (UI) 40 and a function informationacquiring unit 42. The manager 106 is connected to the agent 202 of theprinter 12 (see FIG. 3) via the network 16.

The UI 40 displays a screen (page) of setups of the printer 12, so thatfunctions of the printer 12 can be specified based on user input. The UI40 includes a display unit 402, an input unit 404, a setup storage 406,and a setup reading unit 408. The display unit 402 generates a screenfor specifying functions of the printer 12 and displays the screen on adisplay device (not shown) such as a monitor. The display unit 402receives user input for specifying functions. The input unit 404 is usedby a user to input setups for functions of the printer 12. The inputunit 404 can be an input device such as a mouse or a keyboard. The setupstorage 406 is for storing previous setups for functions of the printer12. The setup reading unit 408 reads the setups for the functions of theprinter 12 saved in the setup storage 406, and sends the setups to afunction information storage 428 of the function information acquiringunit 42, in order to reflect the setups in a setup screen displayed bythe display unit 402.

The function information acquiring unit 42 acquires function informationstored in the MIB 204 (see FIG. 3) of the printer 12 and reflects thefunction information in the setup screen displayed by the display unit402 of the UI 40. The function information acquiring unit 42 includes afunction file storage 422, a device classifying unit 424, a functionfile reading unit 426, and the function information storage 428.

The function file storage 422 includes a first function file describingfunctions common to printers of the same machine type, a second functionfile describing functions common to all of the printers handled by thesame vendor regardless of the machine type of the printer, and a thirdfunction file describing functions common to all of the printersregardless of the machine type of the printer or the vendor.

The device classifying unit 424 classifies the printer 12 into one ofthe following categories according to configuration information acquiredfrom the printer 12 such as the machine name or vendor information.

-   (1) A printer already known to the printer driver 104 (a product of    the same vendor, and the printer driver 104 has a function file    dedicated for the printer)-   (2) A printer unknown to the printer driver 104 (a product of the    same vendor, but the printer driver 104 does not have a function    file dedicated for the printer)-   (3) A printer unknown to the printer driver 104 (a product of a    different vendor, and the printer driver 104 does not have a    function file dedicated for the printer)

The function file reading unit 426 is for reading a function file fromthe function file storage 422 according to the category into which theprinter 12 is classified by the device classifying unit 424. Thefunction information storage 428 temporarily stores, during operation,the function information pertaining to the function described in thefunction file read by the function file reading unit 426. The functioninformation temporarily saved in the function information storage 428 iseventually saved in the setup storage 406 of the UI 40.

FIG. 5 illustrates a data configuration of the MIB 204 shown in FIG. 3.As shown in FIG. 5, the MIB 204 includes a common region 510 and adedicated region 520.

The common region 510 stores information common to all of the printersregardless of the vendor or the machine type.

The dedicated region 520 is a vendor-free region, including amachine-type common region 522 and a machine-type dedicated region 524.The machine-type common region 522 stores function information accordingto a common rule for products of the same vendor. The machine-typededicated region 524 stores function information according to differentrules for each of the machine types that are products of the samevendor.

The following describes some of the operations performed by the computer10.

[Operations]

FIG. 6 is a sequence diagram of an operation performed by the computer10 for displaying a printer function setup screen for the printer 12.

First, in step S101, a user makes a request 25 to specify setups for theprinter 12, using the input unit 404 of the UI 40. Specifically, if theOS is Windows (registered trademark), the user will select “printer” inthe “control panel” and select “property” from the right-click menuwhile selecting the corresponding printer. In response to the requestfrom the user, in step S102, the UI 40 reads the previous setup saved inthe setup storage 406 with the setup reading unit 408. The previoussetup includes the machine name of the printer previously connected tothe communication port 108 and the function setup for the function ofthe previous printer. In step S103, the UI 40 sends, to the functioninformation acquiring unit 42, at least the machine name and thefunction setup included in the setup read by the setup reading unit 408in step S102. In step S104, in the function information acquiring unit42, the function file reading unit 426 reads, from among the pluralityof function files stored in the function file storage 422, a functionfile corresponding to the machine name received from the UI 40 in stepS103. The read function file is saved in the function informationstorage 428. In step S105, the function information storage 428 mergesthe function setup received from the UI 40 in step S103 with thefunction file saved in step S104, and saves them as functioninformation. Next, in step S106, the UI 40 displays a printer setupscreen on the display unit 402 according to the function file into whichthe function setup has been merged at the function information storage428.

Then, in step S107, the user uses the input unit 404 to input a requestin the printer setup screen displayed by the display unit 402 to displaya function setup screen. For example, the function setup screen can bedisplayed in a tab format in the printer setup screen. In response tothe user's request, in step S108, the UI 40 requests the functioninformation acquiring unit 42 to provide function information. In stepS109, the function information acquiring unit 42 sends the functioninformation temporarily saved in the function information storage 428 tothe UI 40. In step S110, the UI 40 causes the display unit 402 todisplay a function setup screen based on this function information.Last, in step S111, the UI 40 saves the function information in thesetup storage 406. The function information saved in the setup storage406 includes information pertaining to the function setup, which is usedas the “previous setup” when a next request to display a printer setupscreen is received.

As described above, when the printer driver 104 is called by theapplication, the printer driver 104 selects the function file of theprinter used previously, and starts operating. Incidentally, immediatelyafter the printer driver 104 is initially installed in the computer 10,the printer driver 104 selects a function file of a default setupspecified at the time of factory shipment or by the printeradministrator.

The function setup screen includes an “update” button (see FIGS. 10A,10B). When this button is pushed by a user, the printer driver 104classifies the printer 12 by acquiring information from the printer 12.

The printer driver 104 selects an appropriate function file according tothe category into which the printer 12 is classified, acquires, from theprinter 12, function information pertaining to the function described inthe selected function file, and operates according to the acquiredfunction information.

The following are detailed descriptions of operations performed by thecomputer 10 for classifying the printer 12.

[First Embodiment]

In the first embodiment, an operation of the computer 10 is described ina case where the printer 12 that is connected is already known to theprinter driver 104 (a product of the same vendor, and the printer driver104 has a function file dedicated for the printer), and corresponds to afunction file already read by the printer driver 104. This operation isdescribed with reference to the sequence diagram shown in FIG. 7.

First, in step S201, a user makes a request to update the function setupscreen, using the input unit 404 of the UI 40. Specifically, the userpresses the “update” button (see FIG. 10A) in the function setup screendisplayed by the display unit 402 of the UI 40. In response to therequest from the user, in step S202, the UI 40 specifies a port name andrequests the manager 106 to perform bidirectional communication with theprinter 12 of the specified port name.

In response to the request from the UI 40, in step S203, the manager 106sends a request to the agent 202 of the printer 12 via the network 16,to acquire PDL information pertaining to the description format of PDL.In step S204, the agent 202 acquires PDL information from the commonregion 510 of the MIB 204, and sends the acquired PDL information to themanager 106. In step S205, the manager 106 sends the PDL informationacquired from the printer 12 to the function information acquiring unit42. In step S206, in the function information acquiring unit 42, thedevice classifying unit 424 confirms whether the PDL description formatof the printer 12 corresponds to the printer driver 104, based on thePDL information acquired from the printer 12.

If the PDL description format of the printer 12 corresponds to theprinter driver 104, in step S207, the function information acquiringunit 42 will cause the manager 106 to send a request to the agent 202 ofthe printer 12 via the network 16, to acquire the machine name. In stepS208, the agent 202 acquires the machine name from the common region 510of the MIB 204, and sends it to the manager 106. In step S209, themanager 106 sends the machine name acquired from the printer 12 to thefunction information acquiring unit 42. In step S210, in the functioninformation acquiring unit 42, the device classifying unit 424 confirmswhether the machine name described in the function file read beforehand(in step S105 in FIG. 6) is the same as the machine name acquired fromthe printer 12.

If the machine name described in the function file is the same as themachine name acquired from the printer 12, in step S211, the functioninformation acquiring unit 42 will cause the manager 106 to send arequest to the agent 202 of the printer 12 via the network 16, toacquire function information pertaining to the function (option)described in the function file read beforehand, from the machine-typededicated region 524 of the MIB 204. In step S212, the agent 202acquires function information from the machine-type dedicated region 524of the MIB 204, and sends the acquired function information to themanager 106. In step S213, the manager 106 sends the functioninformation acquired from the printer 12 to the function informationacquiring unit 42. In step S214, the function information acquiring unit42 saves the function information acquired from the printer 12 in thefunction information storage 428. In step S215, the saved functioninformation is sent from the function information acquiring unit 42 tothe UI 40. In step S216, the UI 40 causes the display unit 402 todisplay the updated function setup screen based on this functioninformation. When the updated function setup screen is displayed, andthe user presses an “apply” button or an “OK” button (see FIG. 10B),which is displayed outside the tab of the function setup screen butinside the same printer setup screen, in step S217, the UI 40 saves thefunction information in the setup storage 406.

FIG. 8 illustrates configuration information stored in the MIB 204 ofthe printer 12 according to the first embodiment. As shown in FIG. 8, anMIB 204 a according to the first embodiment includes a PDL descriptionformat, a machine name, and a vendor identification ID in a commonregion 510 a and a function ID in a machine-type dedicated region 524 a.

The vendor identification ID is for identifying the vendor of theprinter, which can be sent to the manager 106 from the agent 202 of theprinter 12, together with the machine name, in step S208 of FIG. 7. Theprinter driver 104 can confirm whether the printer 12 is already knownbased on the machine name or confirm whether the printer 12 is a productfor the same vendor based on the vendor identification ID. Accordingly,the printer driver 104 can classify the printer 12 into one of the threecategories described above.

The function ID is for identifying the function that can be executed bythe printer. A different function ID is assigned to each function. Thefunction that can actually be used by the printer 12 is represented byoption configuration information including the function ID.

As for the printer 12 to be presently used in the first embodiment, thePDL description format is “XXX”, the machine name of the printer 12 is“PrinterA”, the vendor identification ID is “ooo”, the printer 12 is aproduct of the same vendor as the printer driver 104, and a functionhaving a function ID “2” can be executed.

FIG. 9 illustrates an example of a description of the function fileaccording to the first embodiment. As shown in FIG. 9, in a functionfile 900, there are described a machine name 902 of the printercorresponding to the function file 900 and a function 910 and a function920 that can be used by the printer. The function 910 and the function920 are respectively given a function ID 912 and a function ID 922.

In the first embodiment, “PrinterA” is described as the machine name902. For the first function 910, the function name (option name) isdescribed as “Finisher AAA” and the function ID 912 is described as “1”.For the second function 920, the function name (option name) isdescribed as “Z Unit” and the function ID 922 is described as “2”.

In the following, the operation described with reference to FIG. 7 isdescribed in further detail, assuming that the printer 12 has theconfiguration information shown in FIG. 8 (MIB 204 a) and the printerdriver 104 has read beforehand the function file 900 shown in FIG. 9.

When the manager 106 sends a request to the agent 202 of the printer 12to acquire the machine name (step S207), the agent 202 acquires themachine name=“PrinterA” from the common region 510 a of the MIB 204 a,and sends it to the manager 106 (step S208). The manager 106 sends thismachine name to the function information acquiring unit 42 (step S209).In the function information acquiring unit 42, the device classifyingunit 424 compares the machine name=“PrinterA” acquired from the printer12 with the machine name 902 described in the function file 900 readbeforehand, and determines that the printer 12 corresponds to thefunction file 900 (step S210).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire function information pertaining to the functions 910 and 920described in the function file 900, from the machine-type dedicatedregion 524 a of the MIB 204 a (step S211). In response to theacquisition request from the manager 106, the agent 202 acquiresfunction information pertaining to the functions having function IDscorresponding to the functions 910 and 920 from the machine-typededicated region 524 a. However, the machine-type dedicated region 524 aonly holds the function ID=″2″ corresponding to the second function 920,and therefore, the agent 202 only acquires function informationpertaining to the function 920 having the function ID=“2”, and sends theacquired function information to the manager 106 (step S212). Thefunction information is sent from the manager 106 to the functioninformation acquiring unit 42 (step S213), and is saved in the functioninformation storage 428 (step S214). The function information storage428 can hold information indicating that the function information of thefunction having a function ID=“1” cannot be acquired, and therefore,this function cannot be presently used.

FIGS. 10A and 10B illustrate examples of the function setup screenaccording to the first embodiment. FIG. 10A illustrates a screen basedon the previous function information; FIG. 10B illustrates an updatedscreen that is updated based on the function information acquired fromthe printer to be presently used, which is displayed after the “update”button has been pressed in the screen shown in FIG. 10A.

A function setup screen 110 before being updated displays function namesof all functions (options) 112, 114 of the printer previously used,i.e., “Finisher AAA” and “Z Unit”, and also displays check boxesindicating whether the corresponding functions have actually been ableto be used by the printer. If the previously used printer has beencapable of actually using all of the functions of its machine type, bothof the check boxes will be checked (in an on status). Furthermore, thefunction setup screen 110 includes an “update” button 116, and when auser presses the “update” button 116, the operation shown in FIG. 7 isperformed.

An updated function setup screen 120 is for specifying functions of theprinter to be presently used. If the printer to be presently used is thesame machine type as that of the previously used printer, the functionsetup screen 120 will be similar to the function setup screen 110. Thatis, the function setup screen 120 will display function names “FinisherAAA” and “Z Unit” of all functions (options) 112, 114 of the machinetype, and will also display check boxes indicating whether thecorresponding functions can actually be used by the printer to bepresently used. However, if the printer to be presently used can onlyuse the second function “Z Unit” 114, the check box corresponding to thefirst function 112 will not be checked (in an off status).

As described above, in the first embodiment, a computer confirms that aprinter to be presently used is a known printer of the same machine typeas a printer previously connected to the same communication port. Amongall of the functions that can be executed by a printer of this machinetype, the computer confirms which function can actually be executed bythe printer to be presently used. The computer acquires, from theprinter to be presently used, information pertaining to the functionthat can actually be used by the printer to be presently used. Thecomputer can reflect information as to whether a function can actuallybe used/cannot be used by the present printer, in a setup screen for theprinter.

In a conventional computer, a dedicated printer driver and a dedicatedcommunication port need to be provided for each printer. Thus, in a casewhere the printer that is presently connected is of the same machinetype as a printer that is usually connected to the same communicationport, but has different additional functions, it may not be possible touse all of the functions executable by the printer that is presentlyconnected. However, the computer according to the first embodiment has afile describing all of the functions executable by a printer of aparticular machine type. Therefore, it is possible to connect adifferent printer of the same machine type as the previous printer tothe same communication port to which the previous printer has beenconnected, and appropriately specify the functions of the differentprinter.

[Second Embodiment]

A second embodiment is similar to the first embodiment in that theprinter 12 that is connected is already known to the printer driver 104(a product of the same vendor as the printer driver 104, and the printerdriver 104 has a function file dedicated for the printer). However, theprinter 12 that is connected corresponds to a different function filefrom the function file read beforehand. An operation of the computer 10for this case is described with reference to the sequence diagram shownin FIG. 11.

First, in step S301, a user makes a request to update the function setupscreen, using the input unit 404 of the UI 40. Specifically, the userpresses an “update” button (see FIG. 14A) in the function setup screendisplayed by the display unit 402 of the UI 40. In response to therequest from the user, in step S302, the UI 40 specifies a port name andrequests the manager 106 to perform bidirectional communication with theprinter 12 of the specified port name.

In response to the request from the UI 40, in step S303, the manager 106sends a request to the agent 202 of the printer 12 via the network 16,to acquire PDL information pertaining to the description format of PDL.In step S304, the agent 202 acquires PDL information from the commonregion 510 of the MIB 204, and sends the acquired PDL information to themanager 106. In step S305, the manager 106 sends the PDL informationacquired from the printer 12 to the function information acquiring unit42. In step S306, in the function information acquiring unit 42, thedevice classifying unit 424 confirms whether the PDL description formatof the printer 12 corresponds to the printer driver 104, based on thePDL information acquired from the printer 12.

If the PDL description format of the printer 12 corresponds to theprinter driver 104, in step S307, the function information acquiringunit 42 will cause the manager 106 to send a request to the agent 202 ofthe printer 12 via the network 16, to acquire the machine name. In stepS308, the agent 202 acquires the machine name from the common region 510of the MIB 204, and sends it to the manager 106. In step S309, themanager 106 sends the machine name acquired from the printer 12 to thefunction information acquiring unit 42. In step S310, in the functioninformation acquiring unit 42, the device classifying unit 424 confirmswhether the machine name described in the function file read beforehand(in step S105 in FIG. 6) is the same as the machine name acquired fromthe printer 12.

In the second embodiment, in step S311, the device classifying unit 424determines that the machine name described in the function file readbeforehand and the machine name acquired from the printer 12 aredifferent. In this case, in step S312, the function informationacquiring unit 42 causes the manager 106 to send a request to the agent202 of the printer 12 via the network 16, to acquire vendor information.In step S313, the agent 202 acquires the vendor information from thecommon region 510 of the MIB 204, and sends it to the manager 106. Instep S314, the manager 106 sends the vendor information acquired fromthe printer 12 to the function information acquiring unit 42. In stepS315, in the function information acquiring unit 42, the deviceclassifying unit 424 confirms whether the vendor of the printer 12 isthe same as that of the printer driver 104, based on the vendorinformation acquired from the printer 12.

If the printer 12 is a product of the same vendor as that of the printerdriver 104, in step S316, in the function information acquiring unit 42,the function file reading unit 426 will search the function file storage422 for a function file corresponding to the printer 12, based on themachine name acquired from the printer 12. As a result of the search,when a function file corresponding to the printer 12 is found in thefunction file storage 422, in step S317, the function file reading unit426 reads, from the function file storage 422, the found function filecorresponding to the printer 12, thus overwriting the function filepreviously read.

Next, in step S318, the function information acquiring unit 42 causesthe manager 106 to send a request to the agent 202 of the printer 12 viathe network 16, to acquire function information pertaining to thefunction described in the function file read in step S317, from themachine-type dedicated region 524 of the MIB 204. In step S319, theagent 202 acquires function information from the machine-type dedicatedregion 524 of the MIB 204, and sends the acquired function informationto the manager 106. In step S320, the manager 106 sends the functioninformation acquired from the printer 12 to the function informationacquiring unit 42. In step S321, the function information acquiring unit42 saves the function information acquired from the printer 12 in thefunction information storage 428. In step S322, the saved functioninformation is sent from the function information acquiring unit 42 tothe UI 40. In step S323, the UI 40 causes the display unit 402 todisplay the updated function setup screen based on this functioninformation. When the updated function setup screen is displayed, andthe user presses an “apply” button or an “OK” button (see FIG. 14B),which is displayed outside the tab of the function setup screen butinside the same printer setup screen, in step S324, the UI 40 saves thefunction information in the setup storage 406.

FIG. 12 illustrates configuration information stored in the MIB 204 ofthe printer 12 according to the second embodiment. As shown in FIG. 12,an MIB 204 b according to the second embodiment includes a PDLdescription format, a machine name, and a vendor identification ID in acommon region 510 b and a function ID in a machine-type dedicated region524 b.

As for the printer 12 to be presently used in the second embodiment, thePDL description format is “XXX”, the machine name of the printer 12 is“PrinterB”, the vendor identification ID is “ooo”, the printer 12 is aproduct of the same vendor as the printer driver 104, and a functionhaving a function ID “3” can be executed.

FIG. 13 illustrates an example of a description of the function fileaccording to the second embodiment. As shown in FIG. 13, in a functionfile 1300, there are described a machine name 1302 of the printercorresponding to the function file 1300 and a function 1310 that can beused by the printer. The function 1310 is given a function ID 1312.

In the second embodiment, “PrinterB” is described as the machine name1302. For the function 1310, the function name (option name) isdescribed as “Finisher BBB” and the function ID 1312 is described as“3”.

In the following, the operation described with reference to FIG. 11 isdescribed in further detail, assuming that the printer 12 has theconfiguration information shown in FIG. 12 (MIB 204 b), the printerdriver 104 has read beforehand the function file 900 shown in FIG. 9,and the printer driver 104 reads the function file 1300 shown in FIG. 13found in the function file storage 422, to overwrite the function file900 read beforehand.

When the manager 106 sends a request to the agent 202 of the printer 12to acquire the machine name (step S307), the agent 202 acquires themachine name=“PrinterB” from the common region 510 b of the MIB 204 b,and sends it to the manager 106 (step S308). The manager 106 sends thismachine name to the function information acquiring unit 42 (step S309).In the function information acquiring unit 42, the device classifyingunit 424 compares the machine name=“PrinterB” acquired from the printer12 with the machine name 902 described in the function file 900 readbeforehand (step S310), and determines that the printer 12 does notcorrespond to the function file 900 (step S311).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire vendor information (step S312). In response to the acquisitionrequest from the manager 106, the agent 202 acquires the vendoridentification ID=“ooo” from the common region 510 b of the MIB 204 b,and sends it to the manager 106 (step S313). The manager 106 sends thevendor information ID to the function information acquiring unit 42(step S314). In the function information acquiring unit 42, the deviceclassifying unit 424 confirms whether the printer 12 is a product of thesame vendor as that of the printer driver 104, based on the vendoridentification ID=“ooo” acquired from the printer 12 (step S315). If itis confirmed that the printer 12 is a product of the same vendor as thatof the printer driver 104, in the function information acquiring unit42, the function file reading unit 426 will search the function filestorage 422 for the function file 1300 describing the same machine nameas the machine name=“PrinterB” acquired from the printer 12 (step S316).The function file reading unit 426 reads the function file 1300 found asa result of the search, thus overwriting the function file 900previously read (step S317).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire function information pertaining to the function 1310 describedin the function file 1300, from the machine-type dedicated region 524 bof the MIB 204 b (step S318). In response to the acquisition requestfrom the manager 106, the agent 202 acquires function informationpertaining to the function with the function ID=“3” corresponding to thefunction 1310 from the machine-type dedicated region 524 b, and sendsthe acquired function information to the manager 106 (step S319). Thisfunction information is sent from the manager 106 to the functioninformation acquiring unit 42 (step S320), and saved in the functioninformation storage 428 (step S321).

FIGS. 14A and 14B illustrate examples of the function setup screen(option configuration screen) according to the second embodiment. FIG.14A illustrates a screen based on the previous function information;FIG. 14B illustrates an updated screen that is updated based on thefunction information acquired from the printer to be presently used,which is displayed after the “update” button has been pressed in thescreen shown in FIG. 14A.

The function setup screen 110 before being updated displays functionnames of all functions (options) 112, 114 of the printer previouslyused, i.e., “Finisher AAA” and “Z Unit”, and also displays check boxesindicating whether the corresponding functions have actually been ableto be used by the printer. If the previously used printer has beencapable of actually using all of the functions of its machine type, bothof the check boxes will be checked (in an on status). Furthermore, thefunction setup screen 110 includes the “update” button 116, and when auser presses the “update” button 116, the operation shown in FIG. 11 isperformed.

An updated function setup screen 130 is for specifying functions of theprinter to be presently used. If the printer to be presently used is aproduct of the same vendor as the printer driver 104 and is a knownprinter of a different machine type from the previously used printer,the function setup screen 130 will display the function name of afunction (option) 132 of the machine type of the printer to be presentlyused, i.e., “Finisher BBB”, and will also display a check box indicatingwhether the corresponding function can actually be used by the printerto be presently used.

As shown in FIGS. 14A and 14B, in a case where the printer to bepresently used is a product of the same vendor as that of the printerdriver 104 and is a known printer of a different machine type from thepreviously used printer, when the screen is updated, not only the on/offstatuses of the check boxes change, but the displayed function namesalso change.

As described above, in the second embodiment, a computer confirms that aprinter to be presently used is a known printer of a different machinetype from a printer previously connected to the same communication port.In this case, the computer reads a file describing all of the functionsthat can be executed by a printer of this machine type (of the printerto be presently used). Among all of the functions that can be executedby a printer of this machine type, the computer confirms which functioncan actually be executed by the printer to be presently used. Thecomputer acquires, from the printer to be presently used, informationpertaining to the function that can actually be used by the printer tobe presently used. The computer can reflect information as to whether afunction can actually be used/cannot be used by the present printer, ina setup screen for the printer.

In a conventional computer, a dedicated printer driver and a dedicatedcommunication port need to be provided for each printer. Thus, a printerto be connected needs to be connected to the dedicated printer driverand the dedicated communication port. However, the computer according tothe second embodiment reads a file describing all functions executableby a printer of a particular machine type. Therefore, it is possible toconnect another printer of a different machine type from the previousprinter, to the same communication port to which the previous printerhas been connected, and appropriately specify the functions of the otherprinter.

[Third Embodiment]

In a third embodiment, the printer 12 that is connected is unknown tothe printer driver 104 (the printer driver 104 does not have a functionfile corresponding to the printer 12), but is a product of the samevendor as the printer driver 104. An operation of the computer 10 forthis case is described with reference to the sequence diagram shown inFIG. 15.

First, in step S401, a user makes a request to update the function setupscreen, using the input unit 404 of the UI 40. Specifically, the userpresses an “update” button (see FIG. 18A) in the function setup screendisplayed by the display unit 402 of the UI 40. In response to therequest from the user, in step S402, the UI 40 specifies a port name andrequests the manager 106 to perform bidirectional communication with theprinter 12 of the specified port name.

In response to the request from the UI 40, in step S403, the manager 106sends a request to the agent 202 of the printer 12 via the network 16,to acquire PDL information pertaining to the description format of PDL.In step S404, the agent 202 acquires PDL information from the commonregion 510 of the MIB 204, and sends the acquired PDL information to themanager 106. In step S405, the manager 106 sends the PDL informationacquired from the printer 12 to the function information acquiring unit42. In step S406, in the function information acquiring unit 42, thedevice classifying unit 424 confirms whether the PDL description formatof the printer 12 corresponds to the printer driver 104, based on thePDL information acquired from the printer 12.

If the PDL description format of the printer 12 corresponds to theprinter driver 104, in step S407, the function information acquiringunit 42 will cause the manager 106 to send a request to the agent 202 ofthe printer 12 via the network 16, to acquire the machine name. In stepS408, the agent 202 acquires the machine name from the common region 510of the MIB 204, and sends it to the manager 106. In step S409, themanager 106 sends the machine name acquired from the printer 12 to thefunction information acquiring unit 42. In step S410, in the functioninformation acquiring unit 42, the device classifying unit 424 confirmswhether the machine name described in the function file read beforehand(in step S105 in FIG. 6) is the same as the machine name acquired fromthe printer 12.

In the third embodiment, in step S411, the device classifying unit 424determines that the machine name described in the function file readbeforehand and the machine name acquired from the printer 12 aredifferent. In this case, in step S412, the function informationacquiring unit 42 causes the manager 106 to send a request to the agent202 of the printer 12 via the network 16, to acquire vendor information.In step S413, the agent 202 acquires the vendor information from thecommon region 510 of the MIB 204, and sends it to the manager 106. Instep S414, the manager 106 sends the vendor information acquired fromthe printer 12 to the function information acquiring unit 42. In stepS415, in the function information acquiring unit 42, the deviceclassifying unit 424 confirms whether the vendor of the printer 12 isthe same as that of the printer driver 104, based on the vendorinformation acquired from the printer 12.

If the printer 12 is a product of the same vendor as that of the printerdriver 104, in step S416, in the function information acquiring unit 42,the function file reading unit 426 will search the function file storage422 for a function file corresponding to the printer 12, based on themachine name acquired from the printer 12. In the third embodiment, instep S417, as a result of the search, the function file reading unit 426cannot find a function file corresponding to the printer 12 in thefunction file storage 422. Therefore, in step S418, the function filereading unit 426 reads, from the function file storage 422, a functionfile common to printers of the same vendor regardless of the machinetype, thus overwriting the function file previously read.

Next, in step S419, the function information acquiring unit 42 causesthe manager 106 to send a request to the agent 202 of the printer 12 viathe network 16, to acquire function information pertaining to thefunction described in the function file read in step S418, from themachine-type common region 522 of the MIB 204. In step S420, the agent202 acquires function information pertaining to a function common toprinters of the common vendor, from the machine-type common region 522of the MIB 204, and sends the acquired function information to themanager 106. In step S421, the manager 106 sends the functioninformation acquired from the printer 12 to the function informationacquiring unit 42. In step S422, the function information acquiring unit42 saves the function information acquired from the printer 12 in thefunction information storage 428.

Next, in step S423, the function information acquiring unit 42 causesthe manager 106 to send a request to the agent 202 of the printer 12 viathe network 16, to acquire function information pertaining to thefunction described in the function file read in step S418, from themachine-type common region 510 of the MIB 204. In step S424, the agent202 acquires function information pertaining to the function common toall printers from the common region 510 of the MIB 204, and sends theacquired function information to the manager 106. In step S425, themanager 106 sends the function information acquired from the printer 12to the function information acquiring unit 42. In step S426, thefunction information acquiring unit 42 saves, the function informationacquired from the printer 12 in the function information storage 428.

In step S427, the function information saved in the function informationstorage 428 in steps S422 and S426 is sent from the function informationacquiring unit 42 to the UI 40. In step S428, the UI 40 causes thedisplay unit 402 to display the updated function setup screen based onthis function information. When the updated function setup screen isdisplayed, and the user presses an “apply” button or an “OK” button (seeFIG. 18B), which is displayed outside the tab of the function setupscreen but inside the same printer setup screen, in step S429, the UI 40saves the function information in the setup storage 406.

FIG. 16 illustrates configuration information stored in the MIB 204 ofthe printer 12 according to the third embodiment. As shown in FIG. 16,an MIB 204 c according to the third embodiment includes a PDLdescription format, a machine name, a vendor identification ID, colorinformation indicating the number of colors used for printing, and trayinformation regarding trays for holding printing sheets in a commonregion 510 c, and a function ID in a machine-type common region 522 c.

As for the printer 12 to be presently used in the third embodiment, thePDL description format is “XXX”, the machine name of the printer 12 isunknown (to the printer driver 104), the vendor identification ID is“ooo”, the printer 12 is a product of the same vendor as the printerdriver 104, the color information is “4”, indicating four-colorprinting, the first and second tray information items are “Tray1” and“Tray2”, respectively, and a function having a function ID “1” can beexecuted.

FIG. 17 illustrates an example of a description of the function fileaccording to the third embodiment. As shown in FIG. 17, in a functionfile 1700, there are described a machine name 1702 of the printercorresponding to the function file 1700, and functions 1710, 1720, and1750 that can be used by the printer.

The machine name 1702 does not indicate a specific machine name, butindicates that the printer is a product of the same vendor as theprinter driver 104. For example, in the third embodiment, the machinename 1702 indicates “Printer made by ooo”.

The first function 1710 is given a function ID 1712. In the thirdembodiment, the first function information 1710 pertains to a functionexecuted by printers of a common vendor regardless of the machine type.The function ID 1712 is “1”.

The second function 1720 includes a first sub-function 1730 and a secondsub-function 1740. The first and second sub-functions 1730 and 1740 aregiven function IDs 1732 and 1742, respectively. In the third embodiment,the second function 1720 has a function name (option name) “Color”,indicating whether color printing is possible. In this case, the firstsub-function 1730 is a color printing function, and its function ID 1732is “4”, indicating the number of colors. Meanwhile, the secondsub-function 1740 is a monochrome printing function, and its function ID1742 is “1”, indicating the number of colors.

In the third embodiment, the third function 1750 is described in thefunction file 1700 for acquiring tray information from the printer.

In the following, the operation described with reference to FIG. 15 isdescribed in further detail, assuming that the printer 12 has theconfiguration information shown in FIG. 16 (MIB 204 c), the printerdriver 104 has read beforehand the function file 900 shown in FIG. 9,and the printer driver 104 reads the function file 1700 shown in FIG. 17found in the function file storage 422, to overwrite the function file900 read beforehand.

When the manager 106 sends a request to the agent 202 of the printer 12to acquire the machine name (step S407), the agent 202 acquires themachine name=“(unknown)” from the common region 510 c of the MIB 204 c,and sends it to the manager 106 (step S408). The manager 106 sends thismachine name to the function information acquiring unit 42 (step S409).In the function information acquiring unit 42, the device classifyingunit 424 compares the machine name=“(unknown)” acquired from the printer12 with the machine name 902 described in the function file 900 readbeforehand (step S410), and determines that the printer 12 does notcorrespond to the function file 900 (step S411).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire vendor information (step S412). In response to the acquisitionrequest from the manager 106, the agent 202 acquires the vendoridentification ID=“ooo” from the common region 510 c of the MIB 204 c,and sends it to the manager 106 (step S413). The manager 106 sends thevendor information ID to the function information acquiring unit 42(step S414). In the function information acquiring unit 42, the deviceclassifying unit 424 confirms whether the printer 12 is a product of thesame vendor as that of the printer driver 104, based on the vendoridentification ID=“ooo” acquired from the printer 12 (step S415). If itis confirmed that the printer 12 is a product of the same vendor as thatof the printer driver 104, in the function information acquiring unit42, the function file reading unit 426 will search the function filestorage 422 for a function file describing the same machine name as themachine name=“(unknown)” acquired from the printer 12 (step S416). Whena function file describing the Same machine name as the machinename=“(unknown)” acquired from the printer 12 cannot be found (stepS417), the function file reading unit 426 reads the function file 1700common to printers of the same vendor regardless of the machine typefrom the function file storage 422, thus overwriting the function file900 previously read (step S418).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire function information pertaining to the function 1710 describedin the function file 1700, from the machine-type common region 522 c ofthe MIB 204 c (step S419). In response to the acquisition request fromthe manager 106, the agent 202 acquires function information pertainingto the function with the function ID corresponding to the function 1710from the machine-type common region 522 c. In the third embodiment, themachine-type common region 522 c includes the function ID=“1”corresponding to the first function 1710. Hence, the agent 202 acquiresfunction information pertaining to the function having the functionID=“1” from the machine-type common region 522 c, and sends the acquiredfunction information to the manager 106 (step S420). The functioninformation is sent from the manager 106 to the function informationacquiring unit 42 (step S421), and is saved in the function informationstorage 428 (step S422).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire function information pertaining to the functions 1720 and 1750described in the function file 1700, from the common region 510 c of theMIB 204 c (step S423). In response to the acquisition request from themanager 106, the agent 202 acquires function information correspondingto the functions 1720 and 1750 from the common region 510 c. In thethird embodiment, the common region 510 c includes color information“Color: 4” indicating that the number of colors is four, and therefore,the agent 202 acquires the color information “4” as function informationcorresponding to the function 1720 from the common region 510 c, andsends the acquired function information to the manager 106. Furthermore,in the third embodiment, the common region 510 c includes trayinformation “Tray: Tray1” and “Tray: Tray2”, and therefore, the agent202 acquires “Tray1” and “Tray2” as tray information corresponding tothe function 1750 from the common region 510 c, and sends the acquiredtray information to the manager 106 (step S424). In reality, the colorinformation and the tray information are given different identifiers(OID) in the MIB 204 c, and are thus acquired at different timings. Thefunction information is sent from the manager 106 to the functioninformation acquiring unit 42 (step S425), and is saved in the functioninformation storage 428 (step S426).

Accordingly, the function information storage 428 holds the functioninformation pertaining to functions executed by printers of the commonvendor regardless of the machine type, function information pertainingto the color printing function, and the tray information acquired fromthe printer 12.

FIGS. 18A and 18B illustrate examples of the function setup screen(option configuration screen) according to the third embodiment. FIG.18A illustrates a screen based on the previous function information;FIG. 18B illustrates an updated screen that is updated based on thefunction information acquired from the printer to be presently used,which is displayed after the “update” button has been pressed in thescreen shown in FIG. 18A.

The function setup screen 110 before being updated displays functionnames of all functions (options) 112, 114 of the printer previouslyused, i.e., “Finisher AAA” and “Z Unit”, and also displays check boxesindicating whether the corresponding functions have actually been ableto be used by the printer. If the previously used printer has beencapable of actually using all of the functions of its machine type, bothof the check boxes will be checked (in an on status). Furthermore, thefunction setup screen 110 includes the “update” button 116, and when auser presses the “update” button 116, the operation shown in FIG. 15 isperformed.

An updated function setup screen 140 is for specifying functions of theprinter to be presently used. If the printer to be presently used is aproduct of the same vendor as the printer driver 104, is a printer of adifferent machine type from the previously used printer, and is unknownto the printer driver 104, the function setup screen 140 will displaythe following. That is, the function setup screen 140 will display thefunction names of functions (options) 142, 144, 146, and 148 common toprinters of the same vendor, regardless of the machine type, i.e.,“Color”, “Function Unit 1”, “Tray1”, and “Tray2”, and will also displaycheck boxes indicating whether the corresponding functions can actuallybe used by the printer to be presently used.

As shown in FIGS. 18A and 18B, in a case where the printer to bepresently used is a product of the same vendor as that of the printerdriver 104, is a printer of a different machine type from the previouslyused printer, and is unknown to the printer driver 104, when the screenis updated, not only the on/off statuses of the check boxes change, butthe displayed function names also change.

As described above, in the third embodiment, a computer confirms that aprinter to be presently used is a printer of a different machine typefrom a printer previously connected to the same communication port, isof a machine type unknown to the printer driver 104, and is a product ofthe same vendor as that of the printer driver 104. In this case, thecomputer reads a file describing all of the functions that can beexecuted by all printers of the same vendor. Among all of the functionsthat can be executed by printers of the same vendor, the computerconfirms which function can actually be executed by the printer to bepresently used. The computer acquires, from the printer to be presentlyused, information pertaining to the function that can actually be usedby the printer to be presently used. The computer can reflectinformation as to whether a function can actually be used/cannot be usedby the present printer, in a setup screen for the printer.

In a conventional computer, a dedicated printer driver and a dedicatedcommunication port need to be provided for each printer. Thus, even ifthe printer that is presently connected is a product of the same vendoras that of the printer driver, the printer may not be able to be used.However, the computer according to the third embodiment reads a filedescribing all functions executable by all printers of a particularvendor. Therefore, it is possible to connect a different printer from aprevious printer, which different printer is of the same vendor as thatof the printer driver, to the same communication port to which theprevious printer has been connected, and appropriately specify thefunctions of the different printer.

[Fourth Embodiment]

In a fourth embodiment, the printer 12 that is connected is unknown tothe printer driver 104 (the printer driver 104 does not have a functionfile corresponding to the printer 12), and is a product of a differentvendor from that of the printer driver 104. An operation of the computer10 for this case is described with reference to the sequence diagramshown in FIG. 19.

First, in step S501, a user makes a request to update the function setupscreen, using the input unit 404 of the UI 40. Specifically, the userpresses an “update” button (see FIG. 22A) in the function setup screendisplayed by the display unit 402 of the UI 40. In response to therequest from the user, in step S502, the UI 40 specifies a port name andrequests the manager 106 to perform bidirectional communication with theprinter 12 of the specified port name.

In response to the request from the UI 40, in step S503, the manager 106sends a request to the agent 202 of the printer 12 via the network 16,to acquire PDL information pertaining to the description format of PDL.In step S504, the agent 202 acquires PDL information from the commonregion 510 of the MIS 204, and sends the acquired PDL information to themanager 106. In step S505, the manager 106 sends the PDL informationacquired from the printer 12 to the function information acquiring unit42. In step S506, in the function information acquiring unit 42, thedevice classifying unit 424 confirms whether the PDL description formatof the printer 12 corresponds to the printer driver 104, based on thePDL information acquired from the printer 12.

If the PDL description format of the printer 12 corresponds to theprinter driver 104, in step S507, the function information acquiringunit 42 will cause the manager 106 to send a request to the agent 202 ofthe printer 12 via the network 16, to acquire the machine name. In stepS508, the agent 202 acquires the machine name from the common region 510of the MIB 204, and sends it to the manager 106. In step S509, themanager 106 sends the machine name acquired from the printer 12 to thefunction information acquiring unit 42. In step S510, in the functioninformation acquiring unit 42, the device classifying unit 424 confirmswhether the machine name described in the function file read beforehand(in step S105 in FIG. 6) is the same as the machine name acquired fromthe printer 12.

In the fourth embodiment, in step S511, the device classifying unit 424determines that the machine name described in the function file readbeforehand and the machine name acquired from the printer 12 aredifferent. In this case, in step S512, the function informationacquiring unit 42 causes the manager 106 to send a request to the agent202 of the printer 12 via the network 16, to acquire vendor information.In step S513, the agent 202 acquires the vendor information from thecommon region 510 of the MIB 204, and sends it to the manager 106. Instep S514, the manager 106 sends the vendor information acquired fromthe printer 12 to the function information acquiring unit 42. In stepS515, in the function information acquiring unit 42, the deviceclassifying unit 424 confirms whether the vendor of the printer 12 isthe same as that of the printer driver 104, based on the vendorinformation acquired from the printer 12.

In the fourth embodiment, in step S516, the device classifying unit 424determines that the vendor of the printer 12 and the vendor of theprinter driver 104 are different. In this case, in step S517, thefunction file reading unit 426 reads, from the function file storage422, a function file common to all printers, regardless of the machinetype or the vendor, thus overwriting the function file previously read.

Next, in step S518, the function information acquiring unit 42 causesthe manager 106 to send a request to the agent 202 of the printer 12 viathe network 16, to acquire function information pertaining to thefunction described in the function file read in step S517, from thecommon region 510 of the MIB 204. In step S519, the agent 202 acquiresfunction information pertaining to a function common to all printers,from the common region 510 of the MIB 204, and sends the acquiredfunction information to the manager 106. In step S520, the manager 106sends the function information acquired from the printer 12 to thefunction information acquiring unit 42. In step S521, the functioninformation acquiring unit 42 saves the function information acquiredfrom the printer 12 in the function information storage 428. In stepS522, the function information saved in the function information storage428 is sent from the function information acquiring unit 42 to the UI40. In step S523, the UI 40 causes the display unit 402 to display theupdated function setup screen based on this function information. Whenthe updated function setup screen is displayed, and the user presses an“apply” button or an “OK” button (see FIG. 22B), which is displayedoutside the tab of the function setup screen but inside the same printersetup screen, in step S524, the UI 40 saves the function information inthe setup storage 406.

FIG. 20 illustrates configuration information stored in the MIB 204 ofthe printer 12 according to the fourth embodiment. As shown in FIG. 20,an MIB 204 d according to the fourth embodiment includes a PDLdescription format, a machine name, a vendor identification ID, colorinformation indicating the number of colors used for printing, and trayinformation regarding trays for holding printing sheets in a commonregion 510 d.

As to the printer 12 to be presently used in the fourth embodiment, thePDL description format is “XXX”, the machine name and the vendoridentification ID of the printer 12 are unknown (to the printer driver104), the color information is “4”, indicating four-color printing, andthe first, second, and third tray information items are “Tray1”,“Tray2”, and “Tray2”, respectively.

FIG. 21 illustrates an example of a description of the function fileaccording to the fourth embodiment. As shown in FIG. 21, in a functionfile 2100, there are described a machine name 2102 of the printercorresponding to the function file 2100, and functions 2110 and 2140that can be used by the printer.

The machine name 2102 does not indicate a specific machine name, butindicates that the printer is a product of a different vendor from thatof the printer driver 104. For example, in the fourth embodiment, themachine name 2102 indicates “OtherPrinter”.

The first function 2110 includes a first sub-function 2120 and a secondsub-function 2130. The first and second sub-functions 2120 and 2130 aregiven function IDs 2122 and 2132, respectively. In the fourthembodiment, the first function 2110 has a function name (option name)“Color”, indicating whether color printing is possible. In this case,the first sub-function 2120 is a color printing function, and itsfunction ID 2122 is “4”, indicating the number of colors. Meanwhile, thesecond sub-function 2130 is a monochrome printing function, and itsfunction ID 2132 is “1”, indicating the number of colors.

In the fourth embodiment, the second function 2140 is described in thefunction file 1700 for acquiring tray information from the printer.

In the following, the operation described with reference to FIG. 19 isdescribed in further detail, assuming that the printer 12 has theconfiguration information shown in FIG. 20 (MIB 204 d), the printerdriver 104 has read beforehand the function file 900 shown in FIG. 9,and the printer driver 104 reads the function file 2100 shown in FIG. 21found in the function file storage 422, to overwrite the function file900 read beforehand.

When the manager 106 sends a request to the agent 202 of the printer 12to acquire the machine name (step S507), the agent 202 acquires themachine name=“(unknown)” from the common region 510 d of the MIB 204 d,and sends it to the manager 106 (step S508): The manager 106 sends thismachine name to the function information acquiring unit 42 (step S509).In the function information acquiring unit 42, the device classifyingunit 424 compares the machine name=“(unknown)” acquired from the printer12 with the machine name 902 described in the function file 900 readbeforehand (step S510), and determines that the printer 12 does notcorrespond to the function file 900 (step S511).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire vendor information (step S512). In response to the acquisitionrequest from the manager 106, the agent 202 acquires the vendoridentification ID=“(unknown)” from the common region 510 d of the MIB204 d, and sends it to the manager 106 (step S513). The manager 106sends the vendor information ID to the function information acquiringunit 42 (step S514). In the function information acquiring unit 42, thedevice classifying unit 424 confirms whether the printer 12 is a productof the same vendor as that of the printer driver 104, based on thevendor identification ID=“(unknown)” acquired from the printer 12 (stepS515). If it is confirmed that the printer 12 is a product of adifferent vendor from that of the printer driver 104 (step S516), in thefunction information acquiring unit 42, the function file reading unit426 will read the function file 2100 common to all printers regardlessof the machine type or the vendor from the function file storage 422,thus overwriting the function file 900 previously read (step S517).

The function information acquiring unit 42 causes the manager 106 tosend a request to the agent 202 of the printer 12 via the network 16, toacquire function information pertaining to the functions 2110 and 2140described in the function file 2100, from the common region 510 d of theMIB 204 d (step S518). In response to the acquisition request from themanager 106, the agent 202 acquires function information correspondingto the functions 2110 and 2140 from the common region 510 d. In thefourth embodiment, the common region 510 d includes color information“Color: 4” indicating that the number of colors is four, and therefore,the agent 202 acquires the color information “4” as function informationcorresponding to the function 2110 from the common region 510 d, andsends the acquired function information to the manager 106. Furthermore,in the fourth embodiment, the common region 510 d includes trayinformation “Tray: Tray1”, “Tray: Tray2”, and “Tray: Tray3”, andtherefore, the agent 202 acquires “Tray1”, “Tray2”, and “Tray3” as trayinformation corresponding to the function 2140 from the common region510 d, and sends the acquired tray information to the manager 106 (stepS519). In reality, the color information and the tray information aregiven different identifiers (OID) in the MIB, and are thus acquired atdifferent timings. The function information is sent from the manager 106to the function information acquiring unit 42 (step S520), and is savedin the function information storage 428 (step S521).

Accordingly, the function information storage 428 holds the functioninformation pertaining to the color printing function, and the trayinformation acquired from the printer 12.

FIGS. 22A and 22B illustrate examples of the function setup screen(option configuration screen) according to the fourth embodiment. FIG.22A illustrates a screen based on the previous function information;FIG. 22B illustrates an updated screen that is updated based on thefunction information acquired from the printer to be presently used,which is displayed after the “update” button has been pressed in thescreen shown in FIG. 22A.

The function setup screen 110 before being updated displays functionnames of all functions (options) 112, 114 of the printer previouslyused, i.e., “Finisher AAA” and “Z Unit”, and also displays check boxesindicating whether the corresponding functions have actually been ableto be used by the printer. If the previously used printer has beencapable of actually using all of the functions of its machine type, bothof the check boxes will be checked (in an on status). Furthermore, thefunction setup screen 110 includes the “update” button 116, and when auser presses the “update” button 116, the operation shown in FIG. 19 isperformed.

An updated function setup screen 150 is for specifying functions of theprinter to be presently used. If the printer to be presently used is aproduct of a different vendor from the printer driver 104, the functionsetup screen 150 will display the following. That is, the function setupscreen 150 will display the function names of functions (options) 152,154, 156, and 158 common to all printers, regardless of the machine typeor the vendor, i.e., “Color”, “Tray1”, “Tray2”, and “Tray3”, and willalso display check boxes indicating whether the corresponding functionscan actually be used by the printer to be presently used.

As shown in FIGS. 22A and 22B, in a case where the printer to bepresently used is of a different machine type from the previously usedprinter and is a product of a different vendor from that of the printerdriver 104, when the screen is updated, not only the on/off statuses ofthe check boxes change, but the displayed function names also change.

As described above, in the fourth embodiment, a computer confirms that aprinter to be presently used is a printer of a different machine typefrom a printer previously connected to the same communication port, isof a machine type unknown to the printer driver 104, and is a product ofa different vendor from that of the printer driver 104. In this case,the computer reads a file describing all of the functions that can beexecuted by all of the printers, regardless of the machine type or thevendor. Among all of the functions that can be executed by all of theprinters, the computer confirms which function can actually be executedby the printer to be presently used. The computer acquires, from theprinter to be presently used, information pertaining to the functionthat can actually be used by the printer to be presently used. Thecomputer can reflect information as to whether a function can actuallybe used/cannot be used by the present printer, in a setup screen for theprinter.

In a conventional computer, a dedicated printer driver and a dedicatedcommunication port need to be provided for each printer. Thus, if adedicated printer driver and a dedicated communication port are notprovided for a printer connected to the computer, or if such a dedicatedprinter driver and a dedicated communication port are provided for theprinter, but this printer is connected to another printer driver andanother communication port, the computer will determine that the printeris unknown, and therefore, the printer cannot be used. However, thecomputer according to the fourth embodiment reads a file describing allfunctions executable by any printer. Accordingly, even if a connectedprinter is determined as an unknown printer, it is possible toappropriately specify the functions of this printer.

[Fifth Embodiment]

In a fifth embodiment, the PDL description format of the printer 12 thatis connected does not correspond to the printer driver 104. An operationof the computer 10 for this case is described with reference to thesequence diagram shown in FIG. 23.

First, in step S601, a user makes a request to update the function setupscreen, using the input unit 404 of the UI 40. Specifically, the userpresses an “update” button (see FIG. 10A) in the function setup screendisplayed by the display unit 402 of the UI 40. In response to therequest from the user, in step S602, the UI 40 specifies a port name andrequests the manager 106 to perform bidirectional communication with theprinter 12 of the specified port name.

In response to the request from the UI 40, in step S603, the manager 106sends a request to the agent 202 of the printer 12 via the network 16,to acquire PDL information pertaining to the description format of PDL.In step S604, the agent 202 acquires PDL information from the commonregion 510 of the MIB 204, and sends the acquired PDL information to themanager 106. In step S605, the manager 106 sends the PDL informationacquired from the printer 12 to the function information acquiring unit42. In step S606, in the function information acquiring unit 42, thedevice classifying unit 424 confirms whether the PDL description formatof the printer 12 corresponds to the printer driver 104, based on thePDL information acquired from the printer 12.

In the fifth embodiment, in step S607, the device classifying unit 424determines that the PDL description format of the printer 12 does notcorrespond to the printer driver 104. In this case, in step S608, thefunction information acquiring unit. 42 reports to the UI 40 that thePDL description format is ineligible. Upon receiving this report, instep S609, the UI 40 displays a screen (page) on the display unit 402indicating that functions of the printer 12 cannot be specified.

As described above, according to the fifth embodiment, a computer canconfirm whether the device (e.g., a printer) itself can be used in thefirst place, before acquiring function information pertaining tofunctions that can be used by the device.
